Security questions are a method used to verify a person's identity, often during account recovery or login processes. Users are asked to answer specific questions that only they should know, such as their mother's maiden name or the name of their first pet. This adds an extra layer of protection to online accounts. While security questions can enhance security, they can also pose risks. If the answers are easily guessable or publicly available, such as through social media, they may not effectively protect an account. Therefore, it's important to choose questions and answers that are both memorable and difficult for others to discover.
